Scarpulla, Michael | Suppression of hole-mediated ferromagnetism in Ga1-xMnxP by hydrogen | We report the passivation of the Mn acceptors in Ga1−xMnxP upon exposure to a hydrogen plasma. The as-grown films are nonmetallic and ferromagnetic with a Curie temperature of TC=55 K. After hydrogenation the sample resistivity increases by approximately three orders of magnitude at room tempera... | Ferromagnetic semiconductors; Hydrogenation | 2008 |
